Used as a ligand in coordination chemistry, particularly in the formation of metal complexes for catalytic applications. Its structure allows selective binding to transition metals, enhancing catalytic activity and stability in reactions such as oxidation and C–H activation. Commonly employed in the development of sensors for metal ion detection due to its strong chelating properties and ability to induce color or fluorescence changes upon metal binding. Also utilized in research related to supramolecular chemistry and molecular devices where controlled metal-ligand interactions are required.
